Loft Insulation
I have just had my loft timbers/joists treated for woodworm, and getting
the house rewired soon. After that is all done, I am going to put insulation down. However I have some questions about it. Is there a noticable difference in loft insulation (rockwool rolls) in insulating greater than a 4" depth? The reason I ask is that my joists are 4" in height, and anything greater will mean a bit more planning to ensure that I can still walk and see the joists up there. Also, has anyone noticed a difference between rockwool and other types, such as crown wool? I have checked the u-values and such, and rockwool is a better insulator, but it is also going to cost me about 20% more than crown insulation. (b&q special offer). I really like the idea of using natural insulation such as sheep wool : (http://www.greenbuildingstore.co.uk/ins-thermperf.php) but the price is unbelievable. Any comments/help/advice would be greatly received. Thanks. |
